Charles Guillemet, CTO of Ledger, discusses the future of crypto security and self-custody in the age of AI.

🎙️ As AI agents become more capable, who should control your crypto wallet—you or the AI? Charles Guillemet, CTO of Ledger, joins Alex Richardson at Proof of Talk 2026 to discuss the future of crypto security and why self-custody will become even more important in the age of AI.
